A lication iled December as, as Serial-Io. 238,698.

To all whom't may concern: 0 Be it known that I, Vroron R. Koon'rz, a citizen of the United State s, residing at Waynesboro, in the county of Franklin and State of Pennsylvania, have invented a new and useful Cutter-Head, of which; the following is a specification. y 7

The present invention relates to, improvements incutter heads, the primary-chest of the present invention being the provision of a novel form of-cutter head,-in.which the" tools or diets have theircutting-edgesdisposed tangentially to the bore of the spindle and are movable to and from position by means of a novel form'of mechanism manually controllable, said mechanism being a two-part mechanism one of which parts actuates a locking means to retain the same in locked position when the tools or' such direction and finally oscillated l-to pro-' duce the desired efi'ect in retracting the tools or dies from work engaging position and holding the same in such retracted position or vice versa. y

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides inthe" combination and arrangement-of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed'eangbe made within the scope of what is claimed without departing from the spirit oftthe invention. In the drawings-Figure 1 is a diametrical section throu h the complete head with the parts in lccfied position. -F' l 2 is a front elevation of a portion of t e cutter head showing the tools or dies in proper relative position. Fig. 3 is a section taken on line 33 of Fig. 1. 4 is a cross section through the two rings for actuating the tools showing the locking pin therebetween. Fig. 5 is a detail elevation of a porfor adjusting-the tool or die actuat' vtion of the tool actuatingI member showing the connection thereof to t espindle and per:

mitting a rotar movement to thc-toolor die actuati inem r. Flg. 6 is a cross section taken 1; ough the tool or die actuating member per as; Fig. 7 is aview. illustrating the POIYtIOII of the same carrying'the means Fig. 8 is plan view of the tool or ie acituatmg disk. 9 is an elevation of the toolv or-die carry n disk.

12 and .18 are similar viewsofLthe coacting ring thereof.

Re emng to the drawings, the numeral -1 designates the spindle'whichis adaptedto be connected to-a lathe, the same being hollowas is-the-usual custom and carrying the tool or die holder carrying plate or disk 2, which is :provided. with the three radially disposed slots3 as clearly shown in Fig. 9. 'lhis disk is provided with means for carrying" the too ordie holders 4 which are connected as .shown by means ofholts -8 for movanentto and from the center of the LEI-ate or disk 2,

said bolts or screws 8 as w presently 'appear zbe' I projected into the res active ta en iii lg -disposed slotslO of t e die hol er adjusting and control ring or disk 9 which is mounted foroscillation around the s indle 1 at the rear :of the plate 2, as

cearly shown in Ti '1. In orderto pro-- .vide aimeans for ad ustingnthecontrolling disk 9,1; portion of the periphery as at 11 is-cut away and rovided "withar'teeth,

e operation an control of "which will be set forth-later on. p j

Mounted for oscillatory movement "upon the spindle l to the rear of the disk,9 is a sleeve-12 which is rovided with the integral socketed-plate or tinge-13, which, asclearly shown in Figs. 1 and 6 is'provided-with thedouble diametered portions 14 and 15 to accommodate the plate 2 and the'disk't).

disk.

in the rear Iface of the plate 13 of the sleeve 12 is provided the diametrically -iisposed sockets 16 which constitute a portion of a'looking device, as will presently appear. Mounted intherespective apertures or slots 18 formed through the body of the disk 13 and securely fastened therein are the two sleeves L7, in which isfitted for rotation the smooth or cylindrical ends of the screw 19, said screw '19 being provided with the slotted portions :20 for the introduction :thereto of a screw driver to permit of the rotation of the screw 19, which is in mesh with the gear 11, thus forming a worm gearing to permit of the proper oscillation of the disk 9 to adjust the slots 10 relatively to the tool operating bolts 8. B3 this means the relative cut of the tool is a justed.

The, sleeve 12 as clearly shown, is provided with the diametrically disposed slot 21, while out circumferentially thereof, are the inclined slots 22, which are at an angle of 90 to the slots 21 and are cut at an angle to the axis of the sleeve 12.

.Mounted for oscillation upon the sleeve .12 to the rear of the disk 13 thereof, is the main carrying disk or ring 23, as clearly shown in detail in Figs. 10 and 11, the same, astherein shown, being provided with the diametrically disposed radial slots 24, and

the-peripheral r1mprovided with the yoke receiving recess 26, the purpose of whichwill presently appear. Inthe face of the rim 25 is provided the two diametrically disposed double diametered sockets or aper- .tures. .27, and the single diametered apertures 28", all as clearly shown in Fig. 10.

. Formed in the sleeve portion 37 thereofat diametrically opposite points to each other I and at angles of 90 to the respective slots 24 are the double diameteredapertures 29,

the purpose of which will presently appear. In order to cause the rim 23 torotate with the sleeve 12 and also w1th the spindle '1, the'two pins 30 are threaded-into the each of the, respective pins 30, the two antifrictional rollers 31 and 32, the roller 31 being disposed in its respective slot22 of the sleeve 12 while the roller 32 is disposed in its respective slot 2410f the sleeve 23, thus at these points reducing the friction and providing an anti-frictional connection beco-acting-rin'g. 35,, which is provided with tween the various elements. Mounted for longitudinal sliding movementupon the reduced portion 37 of the member23, is a the circumferential yoke receiving recess 36, which is disposedwhen the members are in properposition as clearly shown in Fig. 1, to assume the position as therein shown and receive the yoke 50, which-is. manually controllable for separating the ring 35 from the ring 23, and, for controlling the actuation of the tools 6, as will presently appear.

In order to provide a means for locking the rin 35 and the ring 23 for movement circum erentially in unison, the rin 35 is provided with the diametrically disposed threaded apertures 38 for the reception of the threaded ends 39 of the cylindrical pins 40, the cylindrical ends being enlarged and disposed for sliding-movement within the double diametered slots or apertures 27 of the disk 25 and for projection therebeyond, when the parts are in the position as shown in Fig. 1, into the locking sockets or recesses 16 of the disk or flange 13.

Additional means for locking andautomatically moving the rings 35 and 23 togetherconsists of the sockets 41 provided at diametrically opposite points in the rear face of the ring 35, and as clearly shown in Fig. 4, said sockets being disposed, as shown in Fig. 12, at angles of 90 to the apertures 38 and having disposed for sliding movement therein, the pins 42 whose heads 43 are mountedin the sockets 41 similarly to a plunger, a spring 44 being disposed upon each pin 42, as clearly shown in Fig. 4, to normally maintain the said pin 42 in the necessary osition to draw the ring 35 upon the shoul ered portion, 37 of the ring 23, the end of the 'pin42 within the aperture 28 of the ring 23 being secured rigidly therein so that when themember or ring 35 is initially operated'to be slid outwardly and longitudinally from the ring 23, the-spring 44 will -be compressed and will automatically return the ring- 35 into the position as shown in Figs. 1 and 4.

From the foregoing description, taken in connection with the drawings it is evident .thatthetool or die holders 4 carrying the tools 'ordies 6 may be readily adjusted relatively toeach other and the work proj'ect-ing through the spindle 1, by means of the worm gearing l9 and 11, and that by reason of the two rings 23 and 35,. and their operating mechanism, .the respective disks 13 and 9 will be actuated to cause the retraction or projection of the die holders 4 which may, as before described and set forth, be locked either in a retracted or projected position, due to the position of the respective locking pins 40 with relation to the flanged disk 13. 7

As shown in Fig. -1, the parts are in locked position with the tools or dies' 6 placed in work engaging position. Assuming that it is desirable to retract the tools or dies 6 and their holders 4, the yoke 50 is operated by beingmoved slightly, to the left as viewed in Fig 1 and as the ring=35 is permitted a slight. longitudinal movement, the same will move to the left until the headed pins 40 are moved out of the recesses 16 of the flan e 13, at which time the rings 23 and 35 Wlll be disengaged from the flange ring 13. A continued movement of the yoke 50 will cause the ring 23 to be moved longitudinally, riding upon the anti-frictional rollers 32 of the pins 30, which due to the rotation of the spindle will impart a slight oscillatory movement to the flange 13 and consequently the tool or die adj usting and actuating disk 9 Whose peculiar shaped slots 10 will now be brought into play to engage the bolts 8 and cause the die holders 4 to move of engagement with thew-ark; The movement of the yoke 50 in the'bpposite direction will permit-of the projection of the tools or dies 6 into work enga ing position and finally when the projecte pins 40 are placed in registration with the sockets 16 of the flange 13, the flange 13 will be locked 'for rotation and against movement as before described.
